Simultaneous Equations Matrix Method : ExamSolutions

[@autonerecords1410]

i have for some completely unknown reason taken math on for an attempt at getting into a engineering bachelor at 62. These videos are helping me get in deeper and deeper. Thankyou ..i think? Seriously great tutorial 👍

[@shellymcdougall4320]

Your explanations are so much more understandable than my teacher's explanation. Thanks a lot for all your help! ;)

you are a living legend

[@ozzyfromspace]

Thank you! I'm doing machine learning and we're right at the beginning, doing linear regressions and such, and we've gotten to the point where we're using normal equations to solve for the model parameters using matrices. I hadn't touched matrices in years really so I was really fuzzy on the mechanics. I appreciate the brush-up :)

[@ExamSolutions_Maths]

Pleased to hear it has offered some help. Good to also hear about real life applications.

[@ExamSolutions_Maths]

Mainly A-level. What you see at present is all I have. I intend to cover the further maths later this year.

[@almanyanyukwenihango7896]

Sir I still don't understand how matrices work and I am about to face my exam

[@malopemdluli5653]

I had difficulties understanding this, but you made it seem easier. I just want to thank you for giving your best for us students to do better. You are much appreciated.

[@ExamSolutions_Maths]

You're very welcome!

Tq sir

[@mybishthing]

can you please do one for matrices with no solutions, one solution, infinite solutions when there is an unknown constant in the square matrix!

[@AHSK-yh5ch]

If for the values that switch would their signs switch as well. And if the signs that switch, what would happen if there is no sign to swap around

[@I3havs]

This was the particular topic,I missed in my class due absenteeism And In exam use to solve the equation normally instead of using matrix method, and each time my marks was deducted. Then before my first preboard,I have finally watched this savage one😅😅😅

[@eliseratcliffe2729]

Hi, I was just wondering,when I tried this out before you explained it, it did (16, -4)*(inverse) but this obviously didn't work. Is it always the case that the inverse comes before the matrix you're multiplying? Thanks for such great videos by the way! :D

[@lamaa.3232]

Yes, inverse always comes first

[@empresssqueen3026]

Thank u

[@ExamSolutions_Maths]

You're welcome. Best wishes to you.

[@afshanzafar7739]

Legends are reborn.

[@hgg219]

I much prefer this method for solving simultaneous equations. Will this work for all simultaneous equations? Or only for those whose inverse exists?

[@ExamSolutions_Maths]

This method works for linear equations. ie of the form ax + by = c and yes, where the inverse exists which is when the determinant does not equal zero.
